pom文件引入

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-data-redis</artifactId>
            </dependency>

spring封装了操作redis的工具RedisTemplate;

@Service
    public class redisService {
        @Autowired
        RedisTemplate redisTemplate;
    
        /**
         * 插入数据
         * @param key
         * @param value
         * @return
         */
        public boolean set(final String key, Object value){
            boolean result = false;
            try{
                ValueOperations<Serializable,Object> operations = redisTemplate.opsForValue();
                operations.set(key,value);
                result = true;
            }catch (Exception e){
                e.printStackTrace();
            }
            return result;
        }
    
        /**
         * 插入带有时间的数据
         * @param key
         * @param value
         * @param expireTime
         * @return
         */
        public boolean set(final String key , Object value , Long expireTime){
            boolean result = false;
            try{
                ValueOperations<Serializable,Object> operations = redisTemplate.opsForValue();
                operations.set(key,value);
                redisTemplate.expire(key,expireTime, TimeUnit.HOURS);
                result = true;
            }catch (Exception e){
                e.printStackTrace();
            }
            return result;
        }
    
        /**
         * 取值
         * @param key
         * @return
         */
        public Object get(final String key){
            Object result = null;
            ValueOperations<Serializable,Object> operations = redisTemplate.opsForValue();
            result=operations.get(key);
            return result;
        }
    
    
    
        /**
         * 列表添加
         * @param k
         * @param v
         */
        public boolean lPush(String k,Object v){
            ListOperations<String, Object> list = redisTemplate.opsForList();
            list.leftPush(k,v);
            return true;
        }
    
        /**
         * 列表获取
         * @param k
         * @param l
         * @param l1
         * @return
         */
        public List<Object> lRange(String k, long l, long l1){
            ListOperations<String, Object> list = redisTemplate.opsForList();
            return list.range(k,l,l1);
        }

测试代码

@RestController
    @CrossOrigin(origins = "*")
    @Api(tags = "测试redis", description = "测试redis")
    @RequestMapping("/redis")
    public class redisController {
        @Autowired
        redisService redisService;
    
        @ApiOperation("insert")
        @PostMapping("/insert")
        public Map insert(@ApiParam("请求参数对象") @RequestBody Map<String, Object> paramMap) {
            Map resultMap = new HashMap();
            String key = paramMap.get("key").toString();
            String value = paramMap.get("value").toString();
            if (redisService.set(key,value)){
                resultMap.put("nb","ok");
            }else{
                resultMap.put("不对","有问题");
            }
            return resultMap;
        }
    
        @ApiOperation("插入列表")
        @PostMapping("/insertList")
        public Map insertList(@ApiParam("请求参数对象") @RequestBody Map<String, Object> paramMap) {
            Map resultMap = new HashMap();
            String key = paramMap.get("key").toString();
            String value =paramMap.get("value").toString();
            if (redisService.lPush(key,value)){
                resultMap.put("nb","ok");
            }else{
                resultMap.put("不对","有问题");
            }
            return resultMap;
        }
    
        @ApiOperation("getList")
        @PostMapping("/getList")
        public Map getList(@ApiParam("请求参数对象") @RequestBody Map<String, Object> paramMap) {
            Map resultMap = new HashMap();
            String key = paramMap.get("key").toString();
            List value = redisService.lRange(key,1,4);
            resultMap.put("value是",value);
            return resultMap;
        }
    
        @ApiOperation("getInfo")
        @PostMapping("/getInfo")
        public Map getInfo(@ApiParam("请求参数对象") @RequestBody Map<String, Object> paramMap) {
            Map resultMap = new HashMap();
            String key = paramMap.get("key").toString();
            String value = redisService.get(key).toString();
            resultMap.put("value是",value);
            return resultMap;
        }
    }

使用swagger-ui辅助测试
